l T 3 Claims. 1 1

of heating means with a novel form of chair which may be used wherever aheated seat is required" for resting, therapeutic or other purposes.

The object of the present invention is to con-J,

struct a heated chair which is easy to make and which may be used incold places where the presence of the occupant is necessary forextended,

intervals, such as in blind when hunting, or when fishing, and even as aremovable seat on vehicles exposed to very low temperatures on longruns.

Another object of the present invention is to; make a collapsible heatedchair having a simple but sturdy construction with a removable heat-jing unit adaptable for using any suitable heating means.

Another object of the present invention is J to make a heated chair asabove with foldable run-t ners for its legs, so that it may be used as asled when desirable.

Another object of the present invention is togmake a heated chair asabove, having hinged, as bestos filled seat portions which, when opened,

will permit the use of the heating unit as a cooking plate and togetherwith the back of the chain.

will provide shielding means against the wind.

Many other and more specific objects will be come apparent in thefollowing detailed descrip-l tion of one illustrative form of chairconstructed; in accordance with this invention, having refer-1' ence tothe accompanying drawings wherein:

Figure 1 is a front elevational view of the chairi j. Figure 2 is asectional side elevational view taken on line 2-2 of Figure 1.

Figure 3 is a sectional plan view taken on line" 3-3 of Figure 2.

As may be seen in the drawings, the chair com-"1 prisesa generallyhollow casing I having a seat chamber 2 and a back chamber 3 suitablyconcaved to receive the back of the occupant when sitting in the chair.

Tubular metal runners 4 hinged at 5 are fold; able, along with thehinged braces 6, intof the bottom of the seat chamber portion. When inthe extended position, as shown in Figures 1 and 2, these runners serveas legs for the chair, and also provide means on which to slide thechair over ice, like a sled. When used in a boat, sleighor othervehicle, the runners 4 may be folded-um der and out of the way.

The seat chamber 2 has asbestos filled covers;

2 by means of threaded lugs l3 integral therewith, passing through holesin the bottom of the seat chamber, and thumb screws I4. The central,intermediate or annular, and the outer cylindrical portions I5, l6 and11 respectively of the burner 9 providing the two concentric slots forthe wicks may be formed on the tank as shown. An annular air space [8 isprovided around the burner and is supplied by air from the outside byair inlet vent l9 and duct when the tank is mounted in place. A seriesof air holes 2| around the burner deliver the air to support combustionof the fuel at the top of the wicks.

A metallic shield 22, having a deflector plate 23 spacedly mounted underthe top of the shield, which may be used as a hot plate for cooking whenthe covers I are raised, is removably mounted in the seat chamber 2 bymeans of lugs 24 which are sprung into loop strips 25 in the .20 bottomof the seat chamber after having first inserted lug 26 in loop strip 21.

' The inside of the exterior wall of the back chamber 3 is lined withinsulating material 28 to reduce loss of heat to the outside. The top of25 the back chamber 3 is provided with exhaust vent In operation, whenthe covers I are closed to form a seat for the chair, the hot gases ofcombustion mixed with excess air warmed thereby, flow out the front ofthe shield 22 as shown by the arrow in the drawings, around the outsidethereof to the bottom of the back chamber and up therethrough to the topthereof where they are emitted through the exhaust vent 29 after havinggiven up more or less of their heat to the seat and the interior wall ofthe back chamber, furnishing the occupant of the chair with the desiredwarmth.

The bottom of the seat chamber may be made adaptable to receive otherforms of heaters such as canned heat for example.

As already indicated above, this chair, known as the sporteeze chair isadapted for many uses.

What I claim is:

1. A portable chair comprising a casing forming a back and seat, a pairof collapsible runners pivotally connected to said casing and serving aslegs for said chair, the seat of said chair comprising a pair of covershingedly connected along one edge of said seat, the opposite edges ofthe covers joining along the middle, the casing forming the back andseat of said chair being hollow, a tank supported by the lower wall ofthe seat casing, and a plurality of wicks supported by the top wall ofsaid tank.

. legs for said chair, the seat of said chair comprising a pair ofcovers hingedly connected along one edge of said seat, the oppositeedges of the covers joining along the middle, heat resisting materialconnected to the bottom of said covers, said casing forming the back andseat of said chair being wall of said tank. 3. A portable chaircomprising a casing forming a back and seat, a pair of collapsiblerunners.

pivotally connected to said casing and serving as legs for said chair,the seat of said chaircomprising'a pair of covers hingedly connectedalong one, edge of said seat, the opposite edges of the covers joiningalong the middle, the casing forming the back and seat of said chairbeing hollow, a tank supported by the lower wallof the seat casing, aplurality-of wickssupported the top wallofsaid tank,a shielddisposedwithin the hollow, seat hav- 4. ing an open end, and a bafilesupported by said shield to deflect heat from said wicks into the hollowseat and back of said casing.
